PORTABLE TRUCK.

Be' it known that I, ARTHUR G. SoHPA'ra, a subject of the Czar of Russia, and res dent of Milwaukee,*in the county of M11- waukee and State of Wisconsin, have 'invented new and useful Improvements-1n Portable Trucks, of which the following is a description reference being bad to the accompanying drawings, which are a part of this specification;

'My invention relates to a portable-conveying' apparatus, and the object of my 1n'-' vention is to produce a type of conveyer that can be used at a considerably steeper in oline than the ordinary push-plate co veye'r. I Another object of my invention is to produce a conveyer with a well balanced frame, self-contained upon a platform, and adapted to rotate on a turntable. Another object of my invention isto con- .struct a conveyer partly in sections, rota-,

table and movable, fittedzupon a" carriage with ordinary road whee1s,independent of rails, and readily put inposition wherever,

it may be required,

To the above purposes my invention consists of certain novel features of construction and arrangement of parts, which will hereinafter be more fully set forth,"pointed' out in'my claims, and illustratedin theacvention;

Fig, 2 is a plan View of the carriage above the rigid part of the 'rotating element";'-

Fig.- 3 is a sectional view on the line 3-3' ofFig.1;and' h Fig. 4 is a sectional view on the line ll of Fig. 1. I

In dealing with machines of the continu' ous type it is evident that the material which is'being handled is evenly distributed over the entire length of the conveyer,'and thus the apparatus is only burdened with a comparatively moderate weight, a fact which*permits a relatively lightconstrud tion' of the mechanism "and its supports: 'The great advantages of band 'conveyers are 'the small driving power required to manipulate them, their a shape.

The supporting frame-work 1 of Fig.1 is

constructed of suitably strong material,

preferably angle iron terminals 3 with diagonally braced-side bars 2 and end bars 4.

in spaced relations, the upper part of saidsupporting frame work extending forward in the direction of its length forming an inclined plane. Mounted fixedly upon said supporting frame member 3is a series of rollers 5 ournaled in suitable bearings 6.

thefshape of a trough. An endless flexible belt 7 running over the terminal pulleys 8 '1 .Said rollers 5 are hollowed out in the mid dle forming a double cone, and assuming to the endless belt 7, the latter withits attachnients traveling over the terminal pul leys '8? so that only one side of the belt is of the rollers o,

for the belt to move sidewise on its rollers, so that the center of the band is notin the assuming a 7 well 'trou'ghed As there 18 SOIIlGtlIIlGS a tendency center of its supports-the employment of same from oscillating or sagging.

The eonveyer has a separate electro 'mo- 1 tor 10, the shaft of which has a worm 10 which is in mesh with the worm or driven wheel 11. The shaft 13 of said driven wheel is journaled in the reinforcedplates 12, said plates being fastened to the side frame members 8. Mounted on the sameshaft 13 and rigidly fastened to the proximities of the worm geared driven wheel without" contacting the same are two pulleys-8' and 8 whichfengage the iImer surface of the belt 7 and cause said belt and the rollers 5 "to revolve; A fixed receiving hopper 14, composed of two cheeks 15 preferably iron ribbed and a rear wall 16 solidly portion 3 is .fulcrumed in suitable,beai'ings but entirely eliminated.

desirable receptacle (not shown in the draw ing). Said-hopper 14 is open at. its outer end to allow a free and unimpaired passage of material of varied volumes. The side plates 17 form protecting plates for the mechanism of the, conveyer.

Having thus far described the appliances of the conveyer to move the material hori zontally, I will not proceed to fully explain the mechanism for, tilting, rota-ting and.

moving said l conveyer.
